Utility-scale solar

The cut-off point is not easy to set. Here's how we have done it, and why

What do we mean by utility-scale?

We define utility-scale solar as projects with a rated output capacity of 4 MWac and above, as noted here.

This threshold applies (unless stated otherwise) in all our publications from 2014 onwards.

The rationale for adopting this threshold is described in the paper on the left.

Pre 2014

Wiki-solar originally adopted a threshold of 10 MWp.

Legislation changes in some markets created a case for redefining the threshold, so we published this paper and sought the views of experts within the industry in a consultation during the second half of 2013.
